Rock Shox are decent forks. While you can still get a cheaper Rock Shox fork that's on the same "level" as a Suntour, you're better off with a Rock Shox. With the Rock Shox, once you start getting into the Rock Shox Silver, you're stepping up a bit in performance. A Rock Shox Silver is a good fork that will offer you a more pleasant riding experience than anything Suntour has to offer. Step up to Rock Shox Gold and Rock Shox Reba and things start looking really bright.
